HIGHWAY GUARD FENCE CONSTRUCTION Filed May 29, 1930 I By Allorney Patented Apr. 14, 1931 ALF JOHNSON, 0F REVLOC, PENNSYLVANIA HIGHW'AY-GUAR-D-FENCE CONSTRUCTION Application filed May 29,

This invention relates to a highway guard fence and has for its primary object to provide, in a manner as hereinafter set forth, a

fence of this character embodying a novel construction and arrangement of parts for colliding with the supporting posts with the resultant damage to the vehicle and posts and possible injury to the occupants of said vehicle.

Other objects of the invention are to provide highway guard fence of the character described which will be comparatively simple in construction, strong, durable, efficient in its use and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention may be come apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characv ters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a top plan view showing a highway guard fence constructed in accordance with this invention with some of the cable supporting brackets omitted from the supporting posts.

Figure 2 is a fragmentary detail view in side elevation on an enlarged scale showing one of the cable supporting brackets or arms.

Figure 3 is a fragmentary detail View on an enlarged scale in horizontal section taken substantially on the line 33 of Figure 2 looking in the direction indicated by the arrows.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a vertical supporting post which is inserted in the ground in any suitable manner, a series of said posts being provided and mounted in spaced relation as is usual.

Disposed vertically against the side of each of the posts 1 which is toward the highway is a substantially U-shaped bracket 2 having an opening in its intermediate portion 1930. Serial No. 457,218.

through which extends an eye bolt 8 which passes transversely through the post and has mounted on its threaded end a washer 4 and a securing nut 5. The reference numeral 6 designates the horizontally disposed eye of said eye bolt 3. The bracket 2 includes the outwardly extending horizontally disposed arms 7 the free ends of which are provided with arcuat-e recesses in vertical alignment with the opening in the eye 6.

A horizontally disposed flat metallic arm 8 has formed integrally on one end, the vertically spaced eyes 9 which are in vertical alignment with the opening in the eye 6,

said eyes 9 being seated in the arcuate recesses in the opposite ends of the bracket 2. A headed pin 10 passes through the eyes 9 and 6 and a cotter key 11 is disposed transversely through the lower end portion of said pin to secure the same in position. The free end portion of the arm 8 has formed therein the longitudinally spaced openings 12 for the passage of the guard cables 13.

The eye bolts 8 constitute means for rigidly clamping the arm 8 in horizontal position against the bracket 2 when the nut 5 is threaded against or toward the post 1. The eyes 9 seat snugly in the recessesin the opposite end of the bracket 2 and in this manner the arms 8 are frictionally held against swinging movement in a horizontal plane on the eye bolts 8 unless subjected to considerable lateral strain, as when engaged by a moving vehicle.

It will thus be seen that I have provided a sf I highway guard fence of a construction whereby a vehicle or other body coming into contact with the guard cables will be held away from the supporting post until said vehicle has been brought to a stop or the speed therew of materially decreased. It will further be apparent that any desired number of cables 13 may be installed by increasing the num' ber of openings 12 in the arms 8. If desired, two or more of the cable supporting structures may be mounted in vertical alignment of each of the posts 1 and the bolts 10 made long enough to pass through all of same.
